Hello.

Just purchased a new CPU case; it's a Raidmax, Scorpio, model 868. Weird thing, no instruction manual. I've put systems together before, so I plowed on ahead anyway.

However, this is the first time I've had a computer case that came with it's own case fans. Prior to this, I've just had the actual CPU fan, and the Power Supply fan. This case has five fans:

Two in back
Two in front
1 in the (see through) side

But, after hooking up all my drives (DVD drive, CD Rewriteable, HDD, etc.), there's only one more power supply cable left from the Power Supply unit. How is it, exactly, I hook up all of those fans?

I went to RaidMax.com, and looked up my case's model number, and there's a .pdf version of the Instruction Manual. But, nowhere in it is there specific instructions on HOW to hook up the fans.

Here's what I'm assuming: do I just "daisy chain" all of the fans together to each other, and then just hook up the one remaining power cable from the Power Supply unit to the remaining case fan wire? Is this the solution? If so, nothing adverse can happen from this, can it? This "chaining together" won't create any kind of bad drain from the power supply, will it? I don't want to burn anything out. This RaidMax Scorpio case came with it's own Power Supply unit, a 450 watt.

Any help, anyone? Thanks ahead of time.

Yes,

Hooking all the fans in parallel will work fine. (all the balck lines together, and all the red lines together).

The current draw shouldn't be a problem since the fans don't drink a lot of power, but just in case; the total current draw will be the sum of the current rating on all the individual fans. Use this total in your current calculations for powwer supply sizing.

Hi,

I usually just plug the fans into HDD's or whatever because fans don't draw all that much power, so if you don't want to daisy chain them all, just plug them into the power supply ports and then into the hdd.

Most case fans can be either connected to the PSU with a 4-pin molex plug OR connected to the motherboard using a small 3-pin ATX fan plug. I assume your fans don't have this "either/or" plug arrangement?
